摘要
A method for the determination of aerodynamic coefficients when simulating aircraft at aviation training device consists in that by means of hardware and software tools of aviation training device performed is the correction of aerodynamic coefficients of aircraft flight dynamics computer model using simplex-planning method. Variable values of aerodynamic coefficients of forces and momentums of aircraft spatial motion recorded by airborne device for flight information registration are rated, initial simplex is selected and difference between parameters of real attitude position and identical parameters simulated by aviation training device hardware and software is plotted using aircraft motion dynamic equation. Then optimum assessed values of recurrent simplex are determined with minimization of a discrepancy between required and calculated values thereof to given value, matrix of corrections for approximate model of standard aircraft at aviation training device, and computer model of aircraft flight dynamics at aviation training device is corrected.
